Field Notes
We went down to Mill Stream behind the Dedham School. We used a net and a kicknet to catch our bugs. We saw lots of bugs swimming about on top of the water. We think we found whirligigs. We put them in a vial and they were swimming around violently on top and under the water. Some other kids found a dobsonfly larva under rocks.
Supporting Evidence
Photo of my evidence.
Whirligig Beetles have two long legs in the front of their body. This one only has one leg because it fell off in the procedure of showing the legs in the picture. I thought it was a water penny at first but water pennies have short front legs. This whirligig beetle has long front legs.
Photo of my evidence.
Whirligig beetles are usually 3mm to 18mm long. This whirligig beetle is 11mm long, average. I thought it was a water penny by just looking at it at first, but a water penny is 1/4 of an inch.
Photo of my evidence.
Whirligig beetles are rounded on the sides of their body and flat on the top. This whirligig is rounded on the sides and flat on the top. This could’ve been a water penny but water pennies are just flat on top.
